Answer:

<h2>The Answer is B. 2 Hydrogen atoms and 1 Oxygen atom.</h2>

Explanation:

The symbol for a water molecule is H20, and if you know that, the answer will be easier than you expect. So, as we now know, a water molecule symbol is H20, which is 2 hydrogen atoms and one oxygen atom, because if a number is in front of an element, then it means that's how many element atoms there is, like O3 means 3 oxygen atoms. But if there is a molecule with no numbers, that just means one of each atom, like salt/sodium chloride, (NaCl).

PIT_PIT [208]

Answer:

1.33 atm

Explanation:

use general gas equation P1 V1/ T1 = P2 V2/ T2

rearrange and make P2 the subject then solve,it should give you 1.33 atm

A reaction is non-spontaneous at any temperature when
slavikrds [6]

Answer:

A reaction is non-spontaneous at any temperature when the Gibbs free energy > 0.

Explanation:

There is a state function, that determines if a reaction is sponaneous or non spontaneous:

ΔG = Gibbs free energy

A reaction is non spontaneous when it does require energy to produce that reaction. It will be spontaneous, when the reaction does not require energy to be occured.

The formula is: ΔG = ΔH - T.ΔS

ΔH → Enthalpy → Energy gained or realeased as heat.

ΔH < 0 → <em>Exothermic reaction. Spontaneity is favored </em>

T  → Temperature

ΔS → Entropy →  Degree of disorder of a system.

When the system has a considered disorder ΔS > 0, disorder increases.

When the system is more ordered, ΔS < 0, disorder decreases.

The reaction will be non spontaneous if, the enthalpy is positive (endothermic reaction) and the ΔS < 0 (disorder decreases). It will not occur if we do not give energy.

ΔG < 0 → Spontaneous reaction

ΔG > 0 → Non spontaneous reaction

ΔG = 0 → System in equilibrium
